MirrorDirectory

This resource class allows you to mirror any existing site. It works by using
the caching module of Jigsaw and by using a different lookup strategy
for the cached resource. It will handle redirections too, so that if the
origin server emits a redirection to an URL that it holds, then the mirror
resource will rewrite the redirection and hand it out as being the target
of the relocation.

Warning: because this resource really does what it claims to do, it
should always be used in conjunction with the
VirtualHostResource.
As Jigsaw will mirror a given site, it will no longer export the
Admin directory, hence were you not to use the virtual host
handling the configuration would no longer be accessible.
